Safety Instructions
Please read these instructions carefully before using the KH Carer to ensure proper operation.
Using of pH electrodes:
Before using the pH electrode, remove the electrode cap so that it can be detected normally.
Before first use, please calibrate the pH electrode
During the use of the pH electrode, it is necessary to avoid drying of the electrode head. After each
test of the pH electrode, the liquid should be stored in the beaker to continue to protect the pH
electrode.
When not in use for a long time, the pH electrode should be stored in an electrode cap with protective
solution
The pH electrode has a service life, which varies according to the use environment. Generally, it
is about one year. During the pH calibration, it will prompt whether the pH electrode should be
replaced.
The KH test solution is stirred at least once a week, otherwise the concentration may be unstable.
The stirring can be shaken or magnetic stirring can be used.
Use protective packaging to protect the appliance from any damage during transport. After unpacking,
dispose of all packaging elements in a manner that will not harm the environment. All materials used

Illustrations and operating instructions
1. Pull the pH electrode (1) down to the position
shown
2. Place the magnetic stirring rotor (2) into the
beaker
3. Place the pH electrode (1) and the drain tube (2) into the beaker (3).
Note: The position of the waste liquid pipe should be close to the inner wall of the beaker to prevent
the magnetic rotor from touching the waste liquid pipe when rotating

2.1.3 KH detection reagent preparation
(If you are purchasing a ready-to-use KH reagent liquid, this step can be ignored)
The following is the dilution operation process of KH detection reagent concentrate (1L):
KH detection reagent concentrate is 20ml per bottle, KH detection reagent concentrate is configured
according to 1 bottle of concentrate with 980g RO water, and one bottle of concentrate can be configured
with 1L of KH detection reagent.
Diagram
Operating instructions
1. Use an electronic scale to weigh 980 grams of
RO water, 980 grams of water corresponds to
980ml of water, RO water can be obtained from
the water dispenser.
Note: Before measuring the water, peel the reagent
bucket on the scale
2. Pour a bottle of KH concentrate into 980 g of
water and gently shake the reagent bucket.
3. Pour the mixed reagent of water and
concentrate in the second step into a part of the
concentrate bottle and wash the concentrate
bottle
4. Re-pour the washed liquid into the reagent
bucket
5. Repeat step (3) (4) once to complete the
dilution of the concentrate

2.1.4 KH enhancer reagent preparation
（If you are purchasing a ready-to-use KH enhancer reagent liquid, this step can be ignored）
KH enhancer reagent is used to enhance the KH of seawater, when the KH is detected low, KH enhancer
reagent needs to be added to make the KH value reach a suitable level.
The following is the operation process of configuring KH enhancer reagent:
Diagram
Operating instructions
1. Weigh 1L of RO water using an electronic
scale
2. Introduce the powder into 1L of RO water
3. Shake the reagent barrel, after 4 hours,
confirm that all KH powder is dissolved and then
use
2.1.5. After completing the installation of KH Carer, configure the App network
Refer to the App Usage Distribution Equipment Chapter
